[Resolved] Add more than one custom field at a time

I am creating a CMS with WordPress. I have nearly two dozen custom fields for more than 40 pages on my site. I would like to be able to add the custom fields quickly, but right now when I enter the key and value, then hit “add custom field” nothing happens, except that this button goes away. When I update the page, the new custom field shows up and I can enter in a new one. This is getting tedious. Is there a way I can add several custom fields without having to refresh or update after each one?

I think this is a bug that was introduced with 3.4.2, I too use custom fields frequently and didn’t see this in previous versions of WP, where I was able to add many different custom fields before saving the page.
